Swami Agung’s comment:
This book is one of the best example for walking the path of self- realization by following the connection with the inner Satguru (in this case, by the principles of Zen Buddhism).
Miyamoto Musashi also known as Shinmen Takezō, Miyamoto Bennosuke or, by his Buddhist name, Niten Dōraku, was a Japanese swordsman and rōnin. Musashi, as he was often simply known, became renowned through stories of his excellent swordsmanship in numerous duels, even from a very young age. He was the founder of the Hyōhō Niten Ichi-ryū or Niten-ryū style of swordsmanship and the author of The Book of Five Rings, a book on strategy, tactics, and philosophy that is still studied today.
